[Elecraft] KIO3B Digital I/O assembly

[Michael Blake]

I am not sure how many of you have noticed the warnings in the K3s and P3 manual to NOT plug a USB B connector into the 8P8C modular jack lableled “RS232/P3” on the rear of the K3s.  This is a VERY important warning but only if you read it prior to inserting the USB cable (twice) into the RS232/P3 jack on the KIO3B.

It was the very first plug I inserted after completing my kit while looking over the radio from the front.  I did it twice because it did not seem to fit correctly:). I did not realize that I had “squished” it for a couple of weeks as I had not tried to use the jack.

Since this little bugger (KIO3B Digital I/O Assy E850646) costs $98, believe it or not, I want to repair my existing board after the replacement arrives tomorrow.  If I did it once I will probably do it again.

My problem is that there are dozens of similar jacks and I need to find the correct manufacturer, part number and source for this particular 8P8C circuit board mounted modular jack. I have the tools and the skills but I lack the correct part.

If anyone from Elecraft could provide me with the proper replacement jack information I would be very grateful.
